AH67.10-P-1000-02SM Notes On Removal/Installation Of Windows


Work on glass panes

^ The use of approved materials and tools is absolutely necessary for proper repair because the material characteristics of the recommended products influence the work results and working time.
^ When working on the glued vehicle windows wear sturdy gloves and eye protection to prevent injuries from cutting and splinters.
^ Bonded points are parts of the unibody construction. Always perform work on bonded windows with particular care.
^ Following fire damage, check adhesive seams and replace if required because the adhesive can be damaged by high heat.

Repair of glass panes

^ Repair of windshields is permissible under the following conditions:
- It is only permissible to repair damage to the outer surface of the windshield.
- The inner surface and plastic foil should not be damaged in any form.
- Ensure that moisture has not penetrated into the damaged point (seal damage point immediately after damage with adhesive tape and repair it as soon as possible).
- The crater at the impact point should not exceed a diameter of 5 mm.
- Cracks extending radially from the impact point should not be longer than 50 mm. They should not end at the rubber window seal and never reach to the outer edge of the window.
Repairing windshield is allowed under the following conditions:
- The repair point must be outside the long-range field of vision.
The long-range field of vision is 29 cm wide and is centered around the center point of the steering wheel
- The area to be repaired must be clean, free of grease and dry.

Replace windows
^ If the paint is damaged when replacing the windows, clean damaged points and treat with anticorrosion agents. Then coat repair point with paint (see paint repair guidelines).
When cleaned and primed never touch bonding surfaces.
^ Before applying adhesive to painted sheet metal, it is necessary to clean the gluing point and treat it with a primer (bonding agent).
^ Do not remove remaining adhesive residues; cut back to a height of approx. 2 mm.
Cut back adhesive residues max. 15 minutes before applying new adhesive bead, because the adhesive material on the cutting surface reacts to the ambient air which can lead to adhesion problems.
^ Always observe curing time of adhesive material to ensure that adhesive bead achieves full strength.
^ For this purpose, open driver and passenger side window for the duration of the curing time to prevent the windshield from being pressed outwards by the air pressure when the doors are closed.
^ Replace spacers damaged during removal. Observe correct distance of spacers to prevent tension in the component.
^ After replacing windshield, rear window or roof, durability is reached after approx. 2 h measured from the time the component is installed. The rated accident strength is achieved only after approx. 8 h.
